如何创建“后台代码"； VS 2019的Blazor组件?

问题描述

我可以创建一个内联组件，例如

I can create an inline component like

<h1>@foo</h1>

@functions {

    string foo = "foo";
}

但是，当我创建仅包含以下内容的Foo.razor时:

However when I create Foo.razor containing just:

<h1>@foo</h1>

和Foo.razor.cs包含:

namespace MyApp.Client.Components {
    public class Foo: ComponentBase {

        public string foo;
    }
}

我得到:

Error   CS0101  The namespace 'MyApp.Client.Components' already contains a definition for 'Foo'

我正在使用最新的VS 2019和Blazor库.

I am using the latest VS 2019 and Blazor libraries.

我在做什么错了?

推荐答案

目前，隐藏代码"是指和.razor视图不能共享相同的名称.

Currently, the "code-behind" and .razor view can't share the same name.

因此，当您具有Foo.razor.cs和Foo.razor时，它将被视为同一文件，从而导致冲突.

So when you have Foo.razor.cs and Foo.razor it is seen as the same file and thus causes a collision.

暂时的解决方法:将Foo.razor.cs重命名为FooBase.cs(或其他名称).

Workaround for now:Rename your Foo.razor.cs to FooBase.cs (or something else).

然后在您的Foo.razor中添加@inherits FooBase
